Route was quite wet after the recent rains. Lower boulderfield has traces of snowmelt making rock slick also. If it has rained a day or two before, the rocks and dirt tend to be very slick as much of the route is in the shade early morning, so use extra caution. The snowfield between Castle and Conundrum is completely melted out, frequent rockfall in the basin. Opted to re-ascend Castle instead of descending the saddle.
